An out-of-bounds read issue was discovered in the HTTP/2 protocol decoder in HAProxy 1.8.x and 1.9.x through 1.9.0 which can result in a crash. The processing of the PRIORITY flag in a HEADERS frame requires 5 extra bytes, and while these bytes are skipped, the total frame length was not re-checked to make sure they were present in the frame.

haproxy: Mishandling of priority flag in short HEADERS frame by HTTP/2 decoder allows for crash
An out-of-bounds read issue was discovered in the HTTP/2 protocol decoder in HAProxy 1.8.x and 1.9.x through 1.9.0 which can result in a crash. The processing of the PRIORITY flag in a HEADERS frame requires 5 extra bytes, and while these bytes are skipped, the total frame length was not re-checked to make sure they were present in the frame.
A flaw was found in HAProxy, versions before 1.8.17 and 1.9.1. Mishandling occurs when a priority flag is set on too short HEADERS frame in the HTTP/2 decoder, allowing an out-of-bounds read and a subsequent crash to occur. A remote attacker can exploit this flaw to cause a denial of service. Those who do not use HTTP/2 are unaffected.
